We come across words like ABS, TCS, EBD.etc. in association with cars everyday. We have tried to explain all these terms with their importance in this post of ours.
1. Anti-Lock Braking System (ABS)- The ABS (Anti-lock Brake System) monitors the speed of each wheel to detect locking. When it detects sudden braking, it will release braking pressure for a moment and then provide optimum braking pressure to each wheel.
2. Electronic Brake Distribution (EBD) - One of the most successful recent refinements to antilock braking systems has been electronic brake force distribution or EBD. EBD is based on the principle that not every wheel needs to put forth the same effort into bringing the car to a stop. EBD is based on the principle that the weight being supported by the wheels of your car isn't evenly distributed. Some wheels carry a heavier load than others and will require more brake force in order to bring the car to a stop without it going out of control. Furthermore, the amount of weight being supported by a wheel shifts during the braking process, so the amount of force necessary at each wheel can change rapidly. An EBD system can not only detect how much weight is being supported by each wheel but change the amount of braking power sent to each wheel on an instant-by-instant basis.
3. Electronic Stability Program (ESP) - ESP helps drivers to avoid crashes by reducing the danger of skidding, or losing control as a result of over-steering. ESP becomes active when a driver loses control of their car. It uses computer-controlled technology to apply individual brakes and help bring the car safely back on track, without the danger of fish-tailing. It is also called as Electronic Stability Control (ESC) and Vehicle Stability Control (VSC).
4. Traction Control System- Traction control helps limit tyre slip in acceleration on slippery surfaces. In the past, drivers had to feather the gas pedal to prevent the drive wheels from spinning wildly on slippery pavement. Many of today's vehicles employ electronic controls to limit power delivery for the driver, eliminating wheel slip and helping the driver accelerate under control. When the traction-control system determines that one wheel is spinning more quickly than the others, it automatically "pumps" the brake to that wheel to reduce its speed and lessen wheel slip. In most cases, individual wheel braking is enough to control wheel slip. However, some traction-control systems also reduce engine power to the slipping wheels. On a few of these vehicles, drivers may sense pulsations of the gas pedal when the system is reducing engine power much like a brake pedal pulsates when the antilock braking system is working. Many people mistakenly believe that traction control will prevent their vehicle from getting stuck in the snow. This couldn't be further from the truth. Traction control does not have the ability to increase traction; it just attempts to prevent a vehicle's wheels from spinning.
5. Airbags- When an accident occurs, airbags inflate faster than you can blink your eye. Airbags are key components in automotive safety systems, and, although we cannot see them perform under normal conditions with the naked eye, they soften the impact of collisions by keeping passengers from contacting the steering wheel, dashboard, front glass, and other parts of the automobile. Usually, airbags are offered for the front two passengers but nowadays you do get 6-airbags in many cars on sale in India. Manufacturers offer upto 8 and 10 airbags.
